Description
2 PCT/1T2016/000055 CABLEWAY INSTALLATION, METHOD FOR ENHANCING SECURITY
OF A CABLEWAY INSTALLATION AND SECURITY SYSTEM FOR A
CABLEWAY INSTALLATION
The present invention relates to cableway installation, a method for enhancing security of a cableway installation and a security system for a cableway installation.
Clearly, the present invention may refer to any type of cableway installation, that, by way of non-exhaustive example, may be a gondola or a chair lift.
Therefore, the present invention is in the field of cableway installations.
Nowadays, are known several security systems for verifying the presence of a passenger on a transport element of a cableway installation and adapted to detect whether the passenger is restrained in safety.
In particular it is known today the security system described in W02012172198 that verify the presence of a passenger on a cableway installation chair and, in the positive case, if the safety bar is closed.
This system provides for projecting an infrared light beam towards the chair to analyze the shadow that the chair produces on a screen, when the chair is at a station for loading/unloading passengers.
An electronic device is programmed to distinguish the shadow produced by the chair occupied by at least one passenger from that of an empty chair and to distinguish the shadow produced by the chair with passenger with thw bar closed from that of the chair with a passenger having the bar open.
This traditional security system is however complex, requiring a screen and an optical sensor that can read the shadow projected on the screen.
The screen, of course, must be near to a passing area of the chair thus can be damaged.
Moreover, this system is little reliable because of the difficulty to distinguish the images on the screen because of the variability in size and posture of the passengers.
In addition, this system does not allow continuous monitoring, along the cableway, thus resulting to be of limited effectiveness.
The problem underlying the present invention is therefore to increase the safety of a cableway installation.
Main aim of the present invention is to provide a security system for cableway installations, a method for enhancing the security of a cableway installation and a cableway installation provided with said system, which provides a solution to such a problem overcoming the above mentioned drawbacks.
Within this aim, it is an task of the present invention to propose a cableway installation that allows to monitor the safety of passengers with greater continuity.
Another task of the present invention is to provide a cableway installation that allows to promptly detect a disabled passenger retention system.
Another object of the invention is to propose a cableway installation which maintains high reliability for safety of the passengers, even in case of adverse weather conditions and/or in the event of fouling and/or degradation of the plant itself.
A further task of the present invention is to propose a safety system applicable to a pre-existing cableway installation and a method for enhancing the security of a pre-existing cableway installation that achieve the tasks indicated above.
This aim, these tasks and others which will become apparent hereinafter are achieved by a cableway installation, by a method for enhancing the security of a cableway installation and a security system for a cableway installation according to the enclosed independent claims.
Detail features of a cableway installation, of the method for enhancing the security of a cableway installation and of a security system for a cableway installation according to the invention are disclosed in the dependent claims.
Further features and advantages of the invention will become apparent from the description of a preferred, but not exclusive, embodiment of a cableway installation, of a method for enhancing the security of a cableway installation and of a security system for a cableway installation according to the invention, illustrated only by way of non-limitative example in the accompanying drawings, in which:

- Figure 1 shows a simplified sketch of a system according to the
3 present invention;
- Figures 2a and 2b illustrate an example of a housing in an access and in a safety configurations.
With particular reference to the above figures, it is indicated with reference 10 a cableway installation comprising at least a housing 11 suitable for transporting passengers and equipped with a safety device 12 which is movable between an access configuration and a safety configuration.
The system 10, according to the present invention, has a particular characteristic in that it comprises:
- radiation emitting means 13;
- reflective means 14, adapted to reflect said radiation;
- receiving means 15, adapted to receive a reflection of the radiation, emitted by reflective means 14.
The radiation emitting means 13, the reflecting means 14 and receiving means 15 according to the present invention are located in the plant 10 in such a way that, in at least one predefined operating condition, the radiation emitting means 13 are facing to the reflecting means 14, for irradiate them, and reflecting means 14 are facing the receiving means 15 to reflect thereto to said radiation.
Furthermore, the reflecting means 14 are fixed on the security device 12 so as to reflect said radiation differently depending on whether the safety device 12 is in the access configuration, or in the safety configuration.
It sould be clear that, according to the present invention, the reflective means may be fixed to the safety device 12 in such positions as to be able to reflect said radiation towards the receiving means 13, only when the safety device is in the access configuration and in the safety configuration.
In other words, during the operation of the system 10, in the predefined operating condition, the reflecting means 14 are irradiated by the radiation emitting means 13, said radiation being reflected towards the receiving means 15, where the reflection pattern or the reflected image, when the safety device 12 is in the access configuration, differs from the reflection pattern or reflected image, when the safety device 12 is in the safety configuration.
In general, the access configuration of the safety device will be a
- Figures 2a and 2b illustrate an example of a housing in an access and in a safety configurations.
With particular reference to the above figures, it is indicated with reference 10 a cableway installation comprising at least a housing 11 suitable for transporting passengers and equipped with a safety device 12 which is movable between an access configuration and a safety configuration.
The system 10, according to the present invention, has a particular characteristic in that it comprises:
- radiation emitting means 13;
- reflective means 14, adapted to reflect said radiation;
- receiving means 15, adapted to receive a reflection of the radiation, emitted by reflective means 14.
The radiation emitting means 13, the reflecting means 14 and receiving means 15 according to the present invention are located in the plant 10 in such a way that, in at least one predefined operating condition, the radiation emitting means 13 are facing to the reflecting means 14, for irradiate them, and reflecting means 14 are facing the receiving means 15 to reflect thereto to said radiation.
Furthermore, the reflecting means 14 are fixed on the security device 12 so as to reflect said radiation differently depending on whether the safety device 12 is in the access configuration, or in the safety configuration.
It sould be clear that, according to the present invention, the reflective means may be fixed to the safety device 12 in such positions as to be able to reflect said radiation towards the receiving means 13, only when the safety device is in the access configuration and in the safety configuration.
In other words, during the operation of the system 10, in the predefined operating condition, the reflecting means 14 are irradiated by the radiation emitting means 13, said radiation being reflected towards the receiving means 15, where the reflection pattern or the reflected image, when the safety device 12 is in the access configuration, differs from the reflection pattern or reflected image, when the safety device 12 is in the safety configuration.
In general, the access configuration of the safety device will be a
4 configuration of the safety device in which the latter does not prevent or hinder access to the housing.
Wherein the safety configuration will be a configuration of the safety device in which the latter prevents the user from leaving the housing 11.
For example, in the embodiment of the plant 10 relative to a chairlift system, the security device may comprise a bar 16, and the housing may comprise a chair 17, possibly with multiple seats, with respect to which the bar 16 is hinged , in a per se conventional way, so that it is movable between a lowered position in which it prevents an user to leave the chair 17, to a raised position in which it allows a used to sit on the chair 17.
In this case the lowered position defines the safety configuration and the raised position defines the access configuration.
These configurations, in relation to the present embodiment, are represented by way of example and not exhaustive in the corresponding Figures 2a and 2b.
It is therefore clear that the present invention allows to detect if a housing 11 has the safety device 12 in the access configuration or in the safety configuration in a simple and fast way.
It is sufficient to analyze the data detected by the receiving means 15 that receive a first image or reflection pattern, in case the safety device is in the access configuration, and a second image configuration or reflection pattern, compared to the first, in the case of it is in the safety configuration.
It is clear that to obtain a continuous monitoring as much as possible of the configuration of the safety device 12, the system 10 will be configured so as to provide a plurality of said predefined operating condition, that is the system 10 will be advantageously configured in such a way that there are a plurality of positions, along its operation path, in which the radiation emitting means 13 are facing to the reflecting means 14, to irradiate, and in which the reflecting means 14 are facing to the receiving means 15 to reflect said radiation towards the latters In other words, during the movement of the housing 11, especially during the ascent along the installation path, the housing 11 will be in a plurality of positions in which the radiation emitting means 13 will be facing to the reflecting means 14 which will be facing the receiving means 15 so as to be able to detect, by means of the latter, the configuration of the safety device 12.
For example, in the case of a cableway installations of the type of chair lifts or gondola lifts, where the housings are constituted by chairs or cabins respectively.
Wherein the safety configuration will be a configuration of the safety device in which the latter prevents the user from leaving the housing 11.
For example, in the embodiment of the plant 10 relative to a chairlift system, the security device may comprise a bar 16, and the housing may comprise a chair 17, possibly with multiple seats, with respect to which the bar 16 is hinged , in a per se conventional way, so that it is movable between a lowered position in which it prevents an user to leave the chair 17, to a raised position in which it allows a used to sit on the chair 17.
In this case the lowered position defines the safety configuration and the raised position defines the access configuration.
These configurations, in relation to the present embodiment, are represented by way of example and not exhaustive in the corresponding Figures 2a and 2b.
It is therefore clear that the present invention allows to detect if a housing 11 has the safety device 12 in the access configuration or in the safety configuration in a simple and fast way.
It is sufficient to analyze the data detected by the receiving means 15 that receive a first image or reflection pattern, in case the safety device is in the access configuration, and a second image configuration or reflection pattern, compared to the first, in the case of it is in the safety configuration.
It is clear that to obtain a continuous monitoring as much as possible of the configuration of the safety device 12, the system 10 will be configured so as to provide a plurality of said predefined operating condition, that is the system 10 will be advantageously configured in such a way that there are a plurality of positions, along its operation path, in which the radiation emitting means 13 are facing to the reflecting means 14, to irradiate, and in which the reflecting means 14 are facing to the receiving means 15 to reflect said radiation towards the latters In other words, during the movement of the housing 11, especially during the ascent along the installation path, the housing 11 will be in a plurality of positions in which the radiation emitting means 13 will be facing to the reflecting means 14 which will be facing the receiving means 15 so as to be able to detect, by means of the latter, the configuration of the safety device 12.
For example, in the case of a cableway installations of the type of chair lifts or gondola lifts, where the housings are constituted by chairs or cabins respectively.
5 In accordance with this example, the housings 18 are hung from a rope tow, which is supported by pillars 19 and driven between two stations 20.
In this case, the radiation emitting and receiving means 13, 15 will be preferably installed on the pylons 19 and/or in the stations 20 so as to irradiate the reflecting means fixed to the safety devices 12 of the housings 11 when they pass in close proximity to or in correspondence of the pylons 19 and /or the stations 20.
The reflecting means 14, to make particularly efficient detection of the configuration of the safety device 12, may be put on the latter in visible positions with respect to the advancement direction of the housing 11 and/or in locations visible from the side of the housing 11, as for example illustrated in figures 2a and 2b.
To obtain a continuous monitoring it will be advantageously possible to install the radiation emitting and receiving means on each pylon 19 and 20 and in each station 20.
In accordance with the present invention, it is therefore possible to ascertain in a simple and fast way whether if the housings 11 are in safety, just by analyzing the signal received by the receiving means 15.
It will also be possible to implement in a simple way a monitoring localized in predefined portions of the system 10 only, or distributed throughout the entire system 10, in order to promptly detect dangerous conditions for users traveling in the housings 11.
Preferably, to avoid interference resulting from emission of light radiation in the visible range and for improved operation in conditions of limited visibility, for example in the presence of fog or clouds, said radiation comprise an infrared radiation.
For compactness and simplicity of installation, the radiation emitting means 13 and the receiving means 15 are preferably integrated in a single emitting-receiving device, such as in a video camera with integrated illuminator.
According to an embodiment which has proved to be particularly simple to
In this case, the radiation emitting and receiving means 13, 15 will be preferably installed on the pylons 19 and/or in the stations 20 so as to irradiate the reflecting means fixed to the safety devices 12 of the housings 11 when they pass in close proximity to or in correspondence of the pylons 19 and /or the stations 20.
The reflecting means 14, to make particularly efficient detection of the configuration of the safety device 12, may be put on the latter in visible positions with respect to the advancement direction of the housing 11 and/or in locations visible from the side of the housing 11, as for example illustrated in figures 2a and 2b.
To obtain a continuous monitoring it will be advantageously possible to install the radiation emitting and receiving means on each pylon 19 and 20 and in each station 20.
In accordance with the present invention, it is therefore possible to ascertain in a simple and fast way whether if the housings 11 are in safety, just by analyzing the signal received by the receiving means 15.
It will also be possible to implement in a simple way a monitoring localized in predefined portions of the system 10 only, or distributed throughout the entire system 10, in order to promptly detect dangerous conditions for users traveling in the housings 11.

For compactness and simplicity of installation, the radiation emitting means 13 and the receiving means 15 are preferably integrated in a single emitting-receiving device, such as in a video camera with integrated illuminator.
According to an embodiment which has proved to be particularly simple to
6 manufacture, to use and to install, the reflecting means 14 advantageously comprise ribbons having a first face fixable to said safety device 12 and the second face adapted to reflect said radiation, such as a reflective band known per se.
To avoid that, in case of bad weather, the efficiency of the radiation emitting means 13 and/or of the receiving means 15 may be affected by the deposit thereon of snow and/or ice and/or moisture in the form of condensate, preferably the system 10 comprises heating means adapted for heating the radiation emitting means 13 and/or the receiving means 15 to remove from therefrom the snow/ice/moisture.

For example, such means may include cleaning brushes arranged for example at particular positions of the plant 10, such as for example in correspondence of the pylons 19 and preferably at the stations 20.
These brushes will be positioned, and possibly automatically activated, to interfere with the parts of the housings where the reflecting means 14 are applied on the safety device 12, so as to remove from the reflecting means 14 the dirt possibly accumulated thereon.
Advantageously, the system 10 includes a control device 21 connected to the receiving means 15 and configured to process an electronic signal received by the latter and to control the functionality of the system 10 in function of the electronic signal.
